Pengtour Audio Storage Solutions — One Factory, Every Audio Form Factor

TWS Earphone Case

TWS Earphone Case

Zero-clearance charging case bay with microfiber-lined slot. Ear tip organizer tray (S/M/L sets). Cable coil slot. Documentation card sleeve. Optional: USB cable port through side wall.

  • Protection Challenge: TWS charging cases suffer surface scratches from repeated insertion and removal into generic cases. Loose earbuds rattle inside oversized cavities, stressing the hinge mechanism and scuffing the glossy finish.
  • Pengtour Engineering: Zero-clearance microfiber-lined charging case slot eliminates friction wear. Precision die-cut ear tip organizer tray holds S/M/L sets individually — no loose items, no rattle.

Over-Ear Headphone Case

Over-Ear Headphone Case

Headband channel engineering (straight or curved arc, per actual fold radius). Earcup isolation: 20mm EVA pad per cup. Internal pocket: cable + 3.5mm adapter. Carrying handle or shoulder strap attachment.

  • Protection Challenge: Over-ear headphones face two failure modes in shipping: stacking pressure permanently bends the headband arc, and prolonged compression degrades ear cushion memory foam — reducing noise isolation and comfort that customers immediately notice on unboxing.
  • Pengtour Engineering: Headband channel engineered to exact fold radius (straight or curved arc per model). 20mm EVA isolation pad per earcup prevents cushion compression. Internal cable + adapter pocket keeps accessories separated from headphone surfaces.

IEM / Monitor Case

IEM / Monitor Case

Custom-cast silicone or die-cut EVA ear shell tray. MMCX / 2-pin cable coil slot. Tool pouch insert for ear tip tools. Brushed aluminum nameplate option.

  • Protection Challenge: Metal-shell IEMs stored together risk metal-on-metal contact scratches between earpieces. Detachable MMCX and 2-pin cables tangle and pull on connector pins during removal, causing intermittent audio failure.
  • Pengtour Engineering: Custom-cast silicone or die-cut EVA ear shell tray with individual earpiece slots. Dedicated MMCX / 2-pin cable coil slot with ≥ 25mm bend radius prevents connector stress. Optional brushed aluminum nameplate for premium retail presentation.

Full Audio Kit Case

Full Audio Kit Case

Multi-tier EVA interior: headphone bay (top tier) + DAC/AMP bay with cable management (bottom tier). Divider system: fixed or configurable. Retail display window on lid optional.

  • Protection Challenge: Multi-SKU audio kits — headphone, DAC/AMP unit, cables, adapters — have mismatched weights and surface hardness. Hard DAC/AMP corners abrade adjacent headphone ear cushions, and cable connectors scratch DAC input ports during transport.
  • Pengtour Engineering: Multi-tier EVA interior: dedicated headphone bay (top tier) fully isolated from DAC/AMP bay with cable management (bottom tier). Fixed or configurable divider system prevents tier-to-tier contact. Optional retail display window on lid for shelf presentation.
